Remarks: This species, originally described in Diplomaragna ( Shear 1990) , has since been transferred to Pterygostegia (Mikhaljova 2000) . However, such transfer requires confirmation. This species is somewhat distinct, displaying only one long anterior angiocoxal process of the posterior gonopod, against two long anterior angiocoxal processes in congeners. The species resembles Koreagna obtecta sp. n. in the small single mesal sheath structure of the posterior gonopod colpocoxite, and the absence of the posterior angiocoxal processes of the posterior gonopods, coupled with a long anterior angiocoxal process sheathed on the front face of the colpocoxite. Also as in K. obtecta , there are 29 body segments, and leg pairs 3–7 are not larger than the other walking legs. However, it differs in the long, entire anterior angiocoxal process, 2–segmented telopodites of the anterior gonopods and exaggerated paraterga. It is obscure if the anterior gonopod coxosternum is fastened to the lower point of an arch formed by the basal part of the telopodite. In any case, this species requires additional comparative examination. It is possible that it will be transferred to the new genus Koreagna .

This species seems to be restricted to Mt. Myohyang–san, North Pyongyang Province, North Korea, its terra typica.

Distribution: North Korea.
